Glass fibre microwave drying equipment greatly improves the working environment of production site

Microwave drying equipment for fiberglass adopts PLC to automatically control drying temperature, humidity and drying time. Touch screen type is selected for man-machine interface, which can flexibly set drying process. The microwave frequency is 2450 MHZ, and the microwave power is designed according to the user's output and water lifting requirement. It is a highly automated refractory drying equipment. Microwave drying equipment for glass fibre is suitable for drying rolled yarn, glass fibre cloth, chopped fibre, filament cake, ply yarn, aluminium silicate fiber felt, ceramic fibre, glass fibre post-treatment drying, glass fibre curing, etc. Characteristics of microwave drying equipment for fiberglass:

1. Selective heating. Because water molecule also absorbs microwave, the microwave power absorbed by the high water content part is more than that absorbed by the low water content part. This is also the feature of selective heating, which can be used to achieve uniform heating and drying.

2, energy saving and high efficiency. Microwave also acts directly on the material, so there is no additional heat loss. The air in the furnace is not heated with the corresponding containers, so the thermal efficiency is very high, the production environment is also significantly improved. Compared with far-infrared heating, it can save 30% electricity.

3, short time and high efficiency. Microwave heating is also a process in which the heated object itself becomes a heater without heat conduction. Microwave penetrates the interior and exterior of the object from all sides and makes the object heated uniformly in a very short time, which greatly shortens the drying time.

p>4. Easy to control and advanced technology. Compared with the conventional method, the equipment is ready to use; there is no thermal inertia, flexible and convenient operation; microwave power can be adjusted, transmission speed can be adjusted. In microwave heating and drying, there is no waste water and no waste gas. It is a safe and harmless high-tech.

Microwave drying equipment has the advantages of bright colour and no yellowing phenomenon, good film formation, fast soaking speed, good ribbon formation of precursor plywood yarn, low moisture content, can reach 1-permil, less than 50% energy saving compared with other drying methods, and shorten drying time by more than five times. In the microwave drying process, the infiltration agent is more effective than the conventional heating drying in bridging the original tiny cracks on the surface of glass fibers. The drying time of precursor is shortened, the time when precursor is in high temperature is reduced, and the strength of precursor is not affected. The comparative advantages of microwave-dried glass fibers (such as yarn balls, silk cake, chopped silk, cloth, etc.) compared with conventional drying (such as steam, electric heating, etc.) are as follows: (1) bright color of glass fibers, without burning phenomenon; (2) good film-forming and fast soaking; (3) good ribbon-forming of raw silk ply yarns; (4) mil content can reach 1-per; (2) suitable for drying rolled yarns, glass fiber cloth and short-cut fibers. Silk cake, plywood yarn, aluminium silicate fiber felt, ceramic fiber, glass fiber post-treatment drying, FRP curing, etc.
